You have a bad card, or the cable is loose or connected to the wrong VGA port.

Why is my monitor is showing it is on but nothing's happening


How old is your monitor. Mine did that and it just quit working one day, I had to buy a new one Hopefully, yours is something else. Is it blank while it is booting up, or has it been on and then goes dark?

Trying to set up 3 monitors in windows 7. using on board dvi to connect to one monitor and on board vga to connect to switch box (which then splits video signal to two vga monitors). can only get the dvi...


Sometimes it is difficult to answer a question without asking very basic questions. Using a DVI and a VGA ports will allow you to have screens with different things showing on them. If you use a splitter, the two monitors connected to the splitter will show the same thing on both screens. Is this what you want? I use a splitter at church to have Powerpoint on the main computer monitor, the program then shows on the screen on the wall and the TV monitor, as well as the second monitor at the computer. My splitter occasionally acts up, and I found that unplugging it and plugging it back in makes it work for another couple months. But a splitter for only two monitors is very cheap, no switch box involved.

I have an Acer X223W monitor. I have been using it with DVI input. I need to switch so that it uses VGA. When I connect the VGA cables, the computer goes into power management mode. I can't get it to...


The VGA section of the Monitor is totally separate circuit than that used by the DVI circuit. Either or will do an automatic switch to what ever circuit communicates via the proper attachment (VG or DVI cable). AS long as the VGA Drivers are up-to-date the operating system should recognize the Video signal. Check the DEVICES and look for Video. Your Monitor should show up if the connection is proper, and if not there, you may have a bad Video Cord.

How do i switch my monitor to vga input?


Plug in the VGA cable to the monitor, and to the computer.

The monitor automatically determines which inputs have a valid signal source.

You can also set the monitor's source of video input to VGA, by going to the On Screen Display menu, and the Switch Video Input option.

Here is the User Manual,

'No signal input and power down' message after switch on.


Remove the data cable from the back of the monitor check what message its giving ? If it shows some message like No VGA cable etc.. it means the monitor is fine.
Checked the computer in safe boot
It could be windows issue

My dell inspiron 530 shows a block with red, white, green, and read, can't get to the my programs????


That "red white green and blue" block is a color pattern tester. that means the monitor is on, but is not receiving a signal, so its running tests. If your monitor has Digital input and VGA input, you may just need to switch inputs. Look for 1 or VGA if youre using the blue hook up. look for 2 or digital or dvi if youre using the larger white hook up. Some monitors also have 'auto detect'. If you are in "auto detect' bbut the color box is still there, then your monitor is not receiving video signal from the computer. It could indicate a bad cable or no signal being sent by the machine. If you try another monitor, you can see if the machine is working. I would try a monitor setting for VGA-1 first, since thats most common.

1) No. The switch color should have been Green

2) No Signal on the monitor, indicates the monitor is not receiving a Video Signal from the computer.

A) Could be due to a faulty monitor cable.
Monitor cable is used on a working computer for a test,
Or,
working computer's monitor cable is used on the Advent for a test.

B) Could be due to the graphics 'engine' on the motherboard, or on the graphics card is bad.

[Graphics 'engine'.
GPU
Graphics Processing Unit.

http://en.wikipedia.org/wiki/GPU ]

If the computer is using Integrated Graphics, the GPU is on the motherboard.

(Integrated Graphics is also referred to as OnBoard Graphics. Meaning On the motherBoard)

You will know if it's Integrated Graphics, because the monitor cable will be plugged into the VGA connector, on the motherboard

http://en.wikipedia.org/wiki/VGA_connector

Since you indicate an adapter was included, to adapt to a different port (Connector), it could be a VGA to DVI adapter, or a DVI to VGA adapter.

Your monitor may just have a VGA connector on the monitor cable.
Hence you would use a female VGA to Male DVI adapter.

Your monitor may be an LCD flat screen monitor, and has a DVI connector on the monitor cable.
Hence you would use a female DVI to Male VGA adapter.

DVI
Digital Visual Interface

http://en.wikipedia.org/wiki/Digital_Visual_Interface

VGA monitors are Analog.
LCD monitors are Digital.

A computer puts out a digital signal.

If a VGA monitor is used, the computer has to alter the Digital signal to an Analog one.
This slows down the video signal.

If your monitor (In any case. Not just this one), is an LCD flat screen monitor, it is best to use a DVI monitor cable, and plug into a DVI port on the computer, if available.

If your monitor is a VGA (CRT. Cathode Ray Tube), monitor, and you have a DVI connection on your computer, using the adapter will do you no good.

The adapter just uses the contact pins for VGA, that are present in that DVI adapter, and hence the DVI connection on the computer.

You're still just getting an Analog VGA signal.

Example of a female VGA to male DVI adapter,

http://www.directron.com/dvi.html

If the Integrated Graphics are suspected to be bad, a graphics card is used in the appropriate expansion slot, for a test.

If the graphics work then, the graphics card is left in service.

After I test the monitor cable my next procedure is to suspect the Power On switch, or the Power Supply, and go to the graphics next.

The reasoning is that Power Supply failure, is the number one cause of computer failure.
The next is the Power On switch, then Electrolytic Capacitors used on the motherboard.

(Specifically, any Electrolytic Capacitors used in the motherboard Voltage Regulator Circuit)

If the Power On switch is bypassed, the diagnosis will reveal if the problem is the switch, or Power Supply.

Bypass the Power On switch, and the Power Supply comes on?
Problem is the Power On switch.

[One Power On switch I have found to fit a lot of computers. The Power On switch goes into the plastic Power On button,

http://www.directron.com/atxswitch.html ]

Bypass the Power On switch, and the Power Supply does Not come on?
The problem is the Power Supply.

The Power On switch is bypassed using a jumper wire, from the green Soft Power On wire, to ANY black Ground wire. The contact made is a brief momentary one.

The jumper wire is used at the back, of the 20, or 24-pin ATX main power cable connector.

Two thing to remember on this situation....

First:

On your laptop make sure you switch the dual mode view on your laptop, if you installed your video driver correctly right click on desktop, select there option switching into dual view or extended view, alternative is hold down the FN button or your laptop keyboard and press the Fucntions key (look for the function key with the monitor icon) press and release it while holding the FN key until there is a video on your external VGA monitor.

Second:

If the settings on your laptop is ready for dual or extended view, look for the SOURCE button or your monitor, if not available look for the AUTO button, pressing the Auto button automatically searches the available signal on the VGA, HDMI, or other sources of video on your monitor.
